Neotropical Entomology 36(5): 685-692 (2007) Diversidade de Vespas Sociais (Hymenoptera: Vespidae) nos Cerrados de Uberlândia, MG RESUMO -Estudos de levantamento de espécies são importantes para o conhecimento dos recursos naturais além de contribuírem com informações de características ecológicas de uma determinada região. Não há estudos dessa natureza abordando vespas sociais no Triângulo Mineiro. O presente estudo investiga a diversidade das espécies encontradas em fragmentos de cerrado em Uberlândia, MG, e sua distribuição temporal. O trabalho de campo foi conduzido de outubro de 2003 a setembro de 2004, realizando-se 43 amostragens utilizando as metodologias de busca ativa e amostragem pontual. Foram encontradas 29 espécies em 10 gêneros, destacando-se Polybia e Polistes com 51,7% dos espécimes coletados. Mischocyttarus cerberus styx Richards representou 26,5% do total de indivíduos registrados para busca ativa e Agelaia pallipes (Olivier) correspondeu a 57,6% para amostragem pontual. Duas espécies apresentaram primeiro registro para Minas Gerais: Polybia striata (Fabricius) e M. cerberus styx. Os fragmentos estudados apresentaram elevado índice de diversidade (H' = 0,66 a 1,16), grande quantidade de espécies raras e poucas espécies comuns. O método de amostragem pontual foi satisfatório para coletar as espécies mais comuns enquanto a busca ativa foi importante para a coleta de espécies pontual, embora algumas espécies só tenham sido coletadas pelo método de amostragem pontual. Esses fatores revelaram que para efetuar um levantamento de vespas uma combinação de diferentes metodologias de coleta parece ser o mais indicado. PALAVRAS-CHAVE: Vespa enxameante, método de amostragem, inventárioABSTRACT -Sudies of species survey are important to know the available natural resources and to this issue, related to social wasps, in the Triângulo Mineiro region. The present study describes the diversity of species found in fragments of the cerrado region in Uberlândia, MG, and their temporal were carried out using active searching (24) and point sampling (19) methodologies. Twenty-nine species were found in 10 genera, Polybia and Polistes corresponding to 51.5% of the total listing. Mischocyttarus cerberus styx Richards represented 26.5% of the total individuals recorded by active searching and Agelaia pallipes (Olivier) corresponded to 57.6% by point sampling. Two species Polybia striata (Fabricius) and M. cerberus styx. The studied fragments presented a high level of diversity (H' = 0.66 to 1.16), a large number of rare species and a few common species. To collect the more common species the point sampling method was satisfactory while active searching was better to collect the rarer species. The active searching by point sampling. These factors showed that in order to carry out a wasp survey, a combination of different collection methodologies seems to be more appropriate.

Abstract:This study provides a list of freshwater fishes of the Parque Nacional da Serra dos Órgãos (PARNASO; Rio de Janeiro state, Brazil) and its surrounding areas. Fish samplings were performed by electrofishing during the dry season (2010 -2011) in three different areas: 1, inside of the PARNASO (2 sites); 2, in the buffer zone (4 sites); and 3, in adjacent areas (8 sites). A total of 47 fish species in 13 families and six orders were recorded. Fish composition within the limits of the PARNASO differed from that recorded in the adjacent area, with the latter having comparatively higher species richness. The buffer area had intermediate ichthyofauna composition between the two other areas. This study enhanced knowledge on the composition and structure of the fish assemblages in PARNASO, by recording the occurrence of six new species within the park that were not included in the Management Plan of this Conservation Unit.

Diversity and Habitat Use of Neotropical Harvestmen (Arachnida: Opiliones) in a Costa Rican Rainforest

et al. 2012

In tropical rain forests, harvestmen assemblages are extremely diverse, with richness often exceeding 25 species. In the neotropics, there are published accounts of harvestmen faunas in South America rainforests (especially Amazonia), but relatively little is known about the community ecology of harvestmen in tropical forests of Central America. In this paper, we provide the first insights into the diverse assemblage of harvestmen inhabiting a wet forest at La Selva Biological Station, Costa Rica. Over five field seasons, we recorded 38 species. During our 2009 field season, we examined variation in species abundance, richness, and composition between adjacent successional forests (young secondary, mature secondary, and primary forests) as well as between distinct habitats (ground/litter layer and shrub/tree layer). Based on night samples (but not day), our results indicate that there are only minor differences in species composition and relative abundance between the forest ages, but no differences in richness. The ground/litter layer and shrub/tree layer habitats differed markedly in species composition, species richness, and relative abundance of several species. Our analysis of covariance supports the hypothesis that leg length is related to climbing behavior for several species belonging to Eupnoi and Laniatores.
